System

The System tab provides device-level administration tools for your WiCAN Pro. This page allows you to manage timezones, backup your configurations, update the firmware, and manage security certificates.

1. General Settings & Actions

Setting / ActionDescription
Local TimezoneSets the device's internal clock to your local region. Note: This must be set correctly for the "Scheduled (Time of Day)" Wakeup feature in the Power Saving tab to trigger accurately.
Reboot WiCANPerforms a soft restart of the WiCAN Pro.
Download ConfigurationBacks up your entire device state (Settings, Automate PIDs, Vehicle Groups, CAN Filters, etc.) into a single .json file. Highly recommended before performing a firmware update!
Upload ConfigurationRestores a previously downloaded .json configuration file. The device will automatically reboot after successfully applying the uploaded settings.
Download Restart HistoryDownloads a diagnostic JSON log detailing the history of device restarts (e.g., wakeups, unexpected resets, planned reboots).

2. Firmware Update

The WiCAN Pro supports Over-The-Air (OTA) firmware updates directly through the web browser.

  1. Download the latest firmware .bin file from the Wambs Forked GitHub Releases page. (Note: The UI will display a notification banner at the bottom of the sidebar if a new version is detected).
  2. Click Choose File and select the .bin file you downloaded.
  3. Click Update.
  4. A progress bar will appear to track the upload. Once it reaches 100%, the device will apply the update and automatically reboot.

!WARNINGDo not disconnect the WiCAN Pro from your vehicle's OBD2 port during a firmware update. Interrupting power while the new firmware is being written can corrupt the device.

3. Certificate Manager

If you are routing data to secure endpoints (like an HTTPS webhook, ABRP, or an MQTT broker utilizing MQTTS), you must manage your SSL/TLS certificates here.

The Certificate Manager allows you to store up to 10 named certificate sets. These sets can then be selected from the dropdown menus in the MQTT or Automate Destinations configurations.

Adding a New Certificate Set

  1. New Cert Name: Provide a unique name for this set (e.g., abrp_prod or my_home_mqtt). Only letters, digits, dashes, and underscores are allowed.
  2. CA Certificate: Upload the Certificate Authority (.pem or .crt) used to verify the server's identity.
  3. Client Certificate & Key: If your server requires mutual TLS (mTLS) authentication, upload your client cert (.pem or .crt) and the associated private key (.pem or .key). Note: You must provide both if you are using mTLS.
  4. Click Add Set.

Managing Existing Sets

Below the upload form is a table of your existing sets, showing exactly which files (CA, Client Cert, Client Key) are included in each.

  • You can safely remove old certificates using the Delete button.
  • Note: The system contains a permanent, read-only default set that cannot be deleted.
